3. How We Use Your Information

We use the information we collect to:

1. Provide, maintain, and improve the App and its features.

4. AI Processing and Data Use

The App uses artificial intelligence services to process your content. You should be aware of the following:

Content Processing: Your drafts and content are sent to AI service providers (including but not limited to Google Gemini and DeepSeek) for processing. This data is transmitted securely and used solely to generate responses for you.

Voice Model: Your voice and writing style data is processed to create vector embeddings stored in our database. These embeddings are used exclusively for your account to personalize AI-generated content.

No Training on Your Data: We do not use your personal content to train general-purpose AI models. Your content is processed in real-time and not retained by third-party AI providers beyond the duration of the API call, subject to their data processing agreements.

Content Discovery: The AI-curated discovery feed is powered by publicly available content sources (RSS feeds, public web content). Your personal data is not shared to generate discovery recommendations.

5. Data Sharing and Disclosure

We do not sell your personal information. We may share your information in the following limited circumstances:

Service Providers: We share data with third-party service providers who perform services on our behalf (hosting, analytics, AI processing, customer support). These providers are contractually obligated to use your data only as directed by us.

Connected Platforms: When you publish content through the App, your content is transmitted to the social media platforms you have connected. This is initiated by you and subject to those platforms’ privacy policies.

Legal Requirements: We may disclose information if required by law, regulation, legal process, or governmental request.

Business Transfers: In the event of a merger, acquisition, or sale of assets, your information may be transferred as part of that transaction. We will notify you of any such change.

With Your Consent: We may share information for other purposes with your explicit consent.

6. Data Storage and Security

Your data is stored on secure cloud infrastructure (Supabase/PostgreSQL) with encryption at rest and in transit. We implement industry-standard security measures including:

1. TLS encryption for all data in transit.
2. AES-256 encryption for data at rest.
3. Row-level security policies ensuring users can only access their own data.
4. Regular security audits and vulnerability assessments.
5. Secure OAuth 2.0 token storage for connected platforms.

While we strive to protect your information, no method of electronic transmission or storage is 100% secure. We cannot guarantee absolute security.
